When 13.0 g of acetylene, C2H2, undergoes complete combustion, 65.5 kJ of heat are released.
a) How much energy is released when one mole of acetylene is burned?
b) Write a balanced chemical equation for the reaction and include the heat value in the equation.
The average bond enthalpy for C-His 413 kJ/mol. 413 kJ of energy is required to break a mole of CH into atoms:
CH(g)→C(g) + H(g), AH=413 kJ
Using this information, and your answer from Part A, calculate the enthalpy change of the reaction from Part B. That is, calculate the energy required to break only the
carbon-carbon bonds in benzene.
Express your answer to four significant figures and include the appropriate units.

- Ethanol, C₂H60, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The combustion of one mole of ethanol releases 326.7 kcal of energy. The combustion of one mole of 2-methylheptane, C8H18, releases 1.306 × 10³ kcal of energy.
